LITTLE ROCK, Ark. (AP) - A conservative group took Arkansas Congressman Rick Crawford of Arkansas to task Wednesday for supporting a tax hike on millionaires last year and asked the public to suggest primary challengers for the Republican lawmaker next year.

The Club for Growth listed Crawford and eight other Republican lawmakers on its primarymycongressman.com website. The site targets congressman the group says serve in safe Republican districts but have scored less than 70 percent on its scorecard on economic issues such as tax cuts.

Chris Chocola, the group's president, said the site would "serve as a tool to hold opponents of economic freedom and limited government accountable for their actions."

Crawford, who won re-election to his east Arkansas seat in November, last year proposed a 5 percent surtax on individual incomes exceeding $1 million a year in exchange for Congress passing a balanced budget amendment. Crawford didn't face a primary opponent last year, but proposed the surtax after filing period for his seat ended.

During his re-election bid, Crawford also said he wouldn't vote to increase the federal budget or borrowing limit without a balanced budget amendment.

Crawford said in a statement released by his office that he disagreed with the group's criticism.

"It really boils down to a fundamental disagreement I have with some so-called conservatives about whether we push for temporary feel-good cuts that vanish in a few years or whether we do the hard work of fighting for permanent spending controls like a balanced budget amendment," Crawford said.
